20100267502 | Sports Grip Sensor - A sports training device including a pressure sensor mounted on the grip of a tennis racket or golf club is provided. The device includes a peizo-electric force sensor to monitor the grip pressure in a circular sensing area located under where palm meets the index finger. The peizo-electric sensor varies its resistance inversely with force applied is connected to an op-amp that uses a variable resistor to deliver an output voltage proportional to the force applied. This voltage triggers a vibrating motor to spin, thus alerting the user that he or she has squeezed too hard. This variable pressure sensor is connected to an alarm that will immediately notify the user when the grip is too tight. The exact amount of pressure for each player and the sports equipment used will vary widely, but can be adjusted to signal when the pressure is too great for the particular use. | 10-21-2010 |

20100273587 | Ball Racket - A ball racket includes a head frame for racket stringing, a shaft unit including first and second tubes non-rotatably fitted to each other to be moved relative to each other along an axis, an actuator disposed within the first tube and having an actuating end and a shank body, an expandable shell disposed between the actuating end and the first tube, and a force transmitting mechanism disposed between the expandable shell and the first tube. Counterclockwise rotation of the actuating end causes the expandable shell and thus the first tube to expand radially so as to generate increased friction between the first and second tubes to thereby guard against relative axial movement between the first and second tubes. Clockwise rotation of the actuating end permits the first tube to axially move relative to the second tube so as to adjust the length of the shaft unit. | 10-28-2010 |
